MACHINE-BEARING CABINET.

SPECIFICATION forming part of Letters Patent No. 709,098, datedSeptember 16, 1902.

Serial No. 102,806. (No model.)

To all whom, it may concern:

Be it known that I, THEODOR KUNDTZ,a citizen of the United States ofAmerica, residing at Cleveland, in the county of Cuyahoga and State ofOhio, have invented certain new and useful Improvements in MachineBearing Cabinets; and I hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to whichit pertains to make and use the same.

This invention relates to improvements in machine-bearing cabinets,wherein a tilting leaf adapted to carry a sewing-machine head,type-writer, or other machine or mechanism is lowered below or occupiesan opening in the top of the cabinet, according as the said leaf is inits depending or upwardly-tilted and horizontal position.

This invention pertains more especially to novel and meritoriousmechanism for operating thesaid load-bearing tilting leaf.

The object of this invention is to provide a simple and inexpensive andreliable and convenient operative connection between the saidload-bearingleaf and a lifting leaf which is hinged to the top of thecabinet.

With this object in view the invention consists in certain features ofconstruction and combinations of parts hereinafter described, andpointed out in the claims.

In the accompanying drawings, Figure I is a topplan of a machine-bearingcabinet embodying my invention. Fig. II is an end elevation, mostly invertical section on line II II,

Fig. I, looking in the direction indicated by the arrow. Fig. IIIis anend elevatiommostly in vertical section and corresponding with Fig. II,except that in Fig. III the load-bearing leaf is shown tilted abouthalf-way. Fig. IV is a front side elevation largelyin section on line VIVI, Fig. I.

Portions are broken away in the drawings to reduce their size.

The cabinet comprises a horizontally-arranged top a, which is provided,preferably centrally, with a rectangular opening a, which extendsvertically through the said top and accommodates the location andoperation of the load-bearing leaf 1) of the cabinet, which leaf ispivoted horizontally, as at b, to the rear portion of the top a. Thepivots b are shown arranged longitudinally of the cabinet in closeproximity to the rear edge of the leaf b. In Figs. I and II and in solidlines, Fig. IV, the leaf 1) is shown in its upwardlytilted andhorizontal position, and therefore occupying the opening a. in the topa. In Fig. III the leaf 1? is shown lowered about half-way, andconsequently depending below the opening a, and in dotted lines, Fig.IV, the said leaf is in its depending position. The leaf 1) is actuatedfrom its upwardlytilted or horizontal position into its dependingposition, or vice versa, according as the sewing-machine head or othermachine or mechanism (not shown) which the said leaf is adapted to bear,is to be conveyed into the cabinet from outside the cabinet,or viceversa.

A leaf 0, which is shown hinged at one end, as at c, to the top Cb,horizontally and transve rsely of the cabinet at the left-hand side ofthe opening a, has the dimensions and arrangement required to render itcapable of being swung over, and thereby closing the opening a orforming an extension of the top a, according as the said leaf isactuated into the one or the other of its extreme positions.

A novel and meritorious operative connection between the leaf 0 and theleaf 5, whereby the latter is tilted downwardly or up wardly, accordingas the former is actuated over the opening af or moved to uncover thesaid opening, is provided and constitutes the subject-matter of thisapplication, and the said operative connection comprises a chain orcable 6, attached at one end, as at e, (see Figs. I, III, and IV,) tothe leaf 0 near the rear edge of the said leaf. The cable 6 extends fromthe leaf 0 to and over a guide sleeve f, which is supported from therear portion of the top a rearward of the opening a, and near theleft-hand end of the said opening. The cable 6 leads from the sheave fdownwardly and inwardly and is operatively connected at its inner endwith a lever h, which is fulcrumed at one end, as at h, horizontally andtransversely of the cabinet to the upright stationary back Z of thecabinet, which back depends from the rear portion of the top a. rearwardof the cable e. The lever his provided upon its forward side with aforwardly-projecting arm 7L2, which engages the under side of thecentral and depressed portionlc of a bar it, which is arranged below andextends transversely of the under side of the leaf 1) centrally betweenthe ends of the said leaf and is secured in any ap proved manner at itsends to the said leaf. The relative arrangement of the bar is and thelever-arm 7L2 is such that the said arm shall remain in engagement withthe bar during the actuation of the leaf 1) from one to the other of itsextreme positions and shall effectually support the said leaf and itsload sewing-machine head or other machine or mechanism (notshown)--Which the said leaf is adapted to bear in the upwardly-tiltedand horizontal position of the said leaf. The lever h is provided with aflange 7L3, which has an outer peripheral surface 71 extendingcircumferentially of the axis of the lever and arranged to affordbearing to and guide the cable e during the actuation of the leaf 1) andin the depending position of the said leaf. The lever h is provided atthe inner end of the peripheral surface of the flange it (see Figs. IIIand IV) with a lug h, which is perforated longitudinally, as at 71 toform a slideway or bearing for an endwise-shiftableexternally-screw-threaded pin m, which extends loosely through the saidlug and has a limited movement endwise. The cable e is attached to thepin 1% at the adjacent end of the lug it and a correspondingly-threadednut is mounted upon and engages the threads of the pin m at the oppositeend of the said lug. A compressible and elastic member such, forinstance, as a sleeve a, of rubberis loosely mounted upon the pin mbetween the nut r and the lug 72 and the arrangement of the parts issuch that the leaf 0 when it has been actuated into a horizontalposition, so as to form an extension of the top (1 upon actuating theload-bearing leaf 6 from its depending position into its upwardly-tiltedand horizontal position, shall pull upon the cable e and the connectednut 0% against the action of the compressible and elastic sleeve ormember a, and thereby positively maintain the lever-arm 77. inengagement with the,

depressed portion 10 of the bar 70 in the upwardly-tilted and horizontalposition of the said leaf 1). I would remark also that the lever h toavoid strain upon its fulcrum by the weight upon its arm 77. in thehorizontal and upwardly-tilted position of the leaf b is provided with abrace-forming arm 77?, arranged, preferably, diametrically opposite thearm h and next forward and close to the inner side of the back Z. Thearm 72" when the load bears downwardly upon the arm 77.2 engages thesaid side of the said back and then performs the function of a brace forthe lever.

The combination, with the top of the cabinet, whichtop has an opening extending vertically therethrough, a stationary backbelow the top rearward of the said opening; a tilting leaf supportedfrom the top and arranged to tilt about a horizontal axis and to occupythe aforesaid opening in its upwardlytilted position, and the tiltingleaf hinged to the top horizontally and transversely of the cabinet atone side of the aforesaid opening, of a lever fulcrumed horizontally andtransversely of the cabinet to the aforesaid back a suitable distancebelow the top and having an arm extending in under and transversely ofand instrumental in supporting the firstmentioned leaf,which lever has abrace-forming arm arranged next to the inner side of the aforesaid back,and an operative connection between the said lever and the aforesaidlifting leaf.
